Starting the school day just one half-hour later produced such "stunning positive results" that a small boarding school decided to make the change permanent.
- The 201 students in the study not only slept later in the mornings, they started to feel so good from having extra sleep that they went to bed earlier.
- Average sleep duration increased by 45 minutes to almost 8 hours a day per student.
- By the end of the study, 54% of the students were getting eight hours of sleep a night compared to just 16% when the study began.
- Students also said they were less sleepy during the day.
The students were enrolled at St. George's boarding school in Rhode Island when Dr. Judith Owens began her study by pushing back the start of classes from 8 AM to 8:30 AM. Dr. Owens is director of the Pediatric Sleep Clinic at the Hasbro Children's Hospital in Providence, RI.
The percentage of students, who told Dr. Owens that they were "somewhat unhappy at least part of the day " fell from 66% to 45% by the end of the study. The percent of students who reported irritability, decreased from 84% to 63%. Only half as many students were tardy for first class by the end of the study, and more were eating breakfast.
The study appears in the Archives of Pediatric and Adolescent Medicine.
